Description

POSTUPAK I UREĐAJ ZA PAKOVANJE PACKAGING PROCEDURE AND DEVICE

Pronalazak se odnosi na postupak za pakovanje neke robe u skupljivo pakovanje kao i na uređaj za izvođenje postupka i na pakovanje od skupljive folije. The invention relates to a procedure for packing some goods in a collapsible package, as well as a device for performing the procedure and a package made of collapsible foil.

Postupak i uređaj treba da služe za pakovanje pokvarljivih prehrambenih proizvoda kao što su mesni proizvodi. Problem koji se javlja jeste to, što se tokom skladištenja i dozrevanja proizvoda mogu gubiti sokovi, što pogoršava trajnost upakovanih proizvodazbog povećanog bujanja klica u sokovima. The method and device should be used for packaging perishable food products such as meat products. The problem that arises is that juices can be lost during storage and ripening of products, which worsens the durability of packaged products due to the increased growth of germs in juices.

U praksi se u najjednostavnijem slučaju komadi mesa stavljaju u odgovarajuće kese od plastičnih foluija i u jednoj mašini sa vakuumskom komorom iz kesa se isisa vazduh posle čega se hermetički zatvaraju. Kako su kese uvek veće od proizvoda, preostaje višak folije i nastaju nabori. Kod korišćenja skupljive folije naknadnim zagrevanjem pakovanja omotač se skuplja i postiže se tesno naleganje folije. Nedostatak ovog načina pakovanja jesu veliki izdaci za radnu snagu. Sledeći je način pakovanja tzv. pakovanje sa dubokim izvlačenjem u vakuumu, poznato iz DE-A-2364565. Tu se iz jedne donje trake folije obrazuju elementi u vidu kutijica u koje se stavljaju proizvodi koji treba da se upakuju. Tako ispunjena kutija sa jednom pokrivnom trakom gornje folije unosi se u jednu vakuumsku komoru gde se iz nje isisa vazduh pa se zatim hermetički zatvara. U komori se dovodi toplota na kutiju načinjenu od donje folije usled čega se aktiviraju sile skupljanja, tako da donja folija tesno nalegne na robu koja se pakuje. Tako obrazovano pakovanje prikazano je na slici 6. Nedostatak mu je u tome što su donja folija i gornja folija u jednom području između proizvoda i zavarene ivice u međusobnom dodiru ali nisu zavarene, i što se u području u kome donja i gornja folija naležu jedna na drugu javljaju nabori. U toku sazrevanja sok iz mesa prelazi u taj nehermetizovan odsečak između donje i gornje folije. In practice, in the simplest case, pieces of meat are placed in appropriate bags made of plastic foil and in a machine with a vacuum chamber, the air is sucked out of the bags, after which they are hermetically sealed. As the bags are always larger than the product, excess foil remains and creases occur. When using shrink film, subsequent heating of the package shrinks the wrap and a tight fit of the film is achieved. The disadvantage of this method of packaging is the high labor costs. The following is the so-called packing method. vacuum deep drawing packaging, known from DE-A-2364565. There, elements in the form of boxes are formed from one lower strip of foil into which the products to be packed are placed. The box thus filled with one cover strip of the upper foil is brought into a vacuum chamber where air is sucked out of it and then it is hermetically sealed. In the chamber, heat is applied to the box made of the bottom film, as a result of which the shrinking forces are activated, so that the bottom film fits tightly on the goods being packed. The package formed in this way is shown in Figure 6. Its disadvantage is that the lower foil and the upper foil in one area between the product and the welded edges are in contact with each other but are not welded, and in the area where the lower and upper foil are placed on top of each other, folds appear. During ripening, the juice from the meat passes into that non-hermetic section between the lower and upper foil.

Iz EP-A-127016 poznat je jedan postupak po kome se radi skupljanja pakovanja dobijenog dubokim izvlačenjem vrši zagrevanje parom. I ovde postoje isti nedostaci kao kod napred opisanog pakovanja. From EP-A-127016 a method is known, according to which, in order to shrink the packaging obtained by deep drawing, steam heating is performed. Here, too, there are the same drawbacks as with the previously described packaging.

Cilj je pronalaska da se ostvari jedan postupak i uređaj kao i jedno pakovanje koje će ostvariti dugo trajanje životnih namirnica kao što jc meso, pri čemu pakovanje treba da ima odgovarajući spoljni izgled za iznošenje na tržište. The aim of the invention is to realize a process and a device as well as a package that will achieve a long shelf life of foodstuffs such as meat, whereby the package should have a suitable external appearance for bringing it to the market.

Ovaj je cilj ostvaren postupkom opisanim u patentnom zahtevu 1, uređajem opisanim u patentnom zahtevu 5 i pakovanjem opisanim u patentnom zahtevu 9. This goal is achieved by the method described in claim 1, the device described in claim 5 and the package described in claim 9.

Kako je prikazano na slici 1, mašina za pakovanje obuhvata okvir 1, bočni zid 2 i noseće noge 3. Na okviru su postavljeni, jedan iza drugog, od ulazne do izlazne strane, uređaj 4 za oblikovanje, odnosno za duboko izvlačenje, i uređaj 5 za isisivanje vazduha i za zavarivanje. As shown in Figure 1, the packaging machine includes a frame 1, a side wall 2 and supporting legs 3. On the frame are placed, one behind the other, from the entrance to the exit, a device 4 for shaping, i.e. for deep drawing, and a device 5 for exhausting air and for welding.

Kao što se vidi na slici 1, sa ulazne strane predviđeno je dovođenje donje folije 7. Ova će donja folija biti vođena od ulazne strane kroz uređaje do kraja na izlaznoj strani. Za vođenje su na bočnim stranama predviđeni kružeći lanci koji na ulaznoj strani bočno stežu dovedenu donju foliju i, držeći je jednim prethodno izabranim prednaponom, vode je do izlazne strane. As can be seen in Figure 1, from the input side it is planned to supply the bottom foil 7. This bottom foil will be guided from the input side through the devices to the end on the output side. For guidance, circling chains are provided on the sides, which laterally clamp the supplied lower foil on the inlet side and, holding it with a pre-selected bias, guide it to the outlet side.

Na poznat se način u uređaju 4 za oblikovanje dubokim izvlačenjem olikuju kutije 8. One se iza uređaja za oblikovanje pune proizvodom 9 koji treba da se upakuje. In a known manner, the boxes 8 are shaped in the forming device 4 by deep drawing. They are filled behind the forming device with the product 9 to be packed.

Na slici 1 se vidi da okvir ima jedan dodati nosač 11 na kome je kotur sa namotanom gornjom folijom 10. Preko odgovarajućih koturova za promenu pravca, gornja se folija pre ulaska u uređaj 5 za isisivanje vazđuha i za zavarivanje dovodi na gornju stranu donje folije 7 kao nazovi poklopac za kutije 8. I donja folija 7 kao i gornja folija 8 izvedene su kao skupljive folije. In Figure 1, it can be seen that the frame has one additional support 11 on which there is a reel with a wound upper foil 10. Through the appropriate reels for changing the direction, the upper foil before entering the device 5 for extracting air and for welding is brought to the upper side of the lower foil 7 as the so-called lid for boxes 8. Both the lower foil 7 and the upper foil 8 are designed as collapsible foils.

Uređaj 5 za isisivanje vazđuha i za zavarivanje načinjen je tako, da se jedan donji deo 13 kreće u smeru strelice 14 ka jednom gornjem delu 15, tako da se uređaj hermetički zatvara. Na način poznat iz pomenutog DE-A-2364565 vrši se isisivanje vazđuha i zavarivanje i naleganje stišljive donje folije na upakovan proizvod. Ovako načinjeno pakovanje ima, kako je prikazano na slici 6, jednu zavarenu ivicu 16 i jedan odsečak stisnute donje folije 7 i gornje folije 10 koji tesno naleže na upakovan proizvod. Dalje se između odsečaka folija koji naležu na proizvod i zavarene ivice 16 nalazi odsečak 17 u kome donja folija 7 i gornja folija 10 tesno naležu jedna na drugu a da nisu međusobno zavarene. The device 5 for exhausting air and for welding is made in such a way that one lower part 13 moves in the direction of the arrow 14 towards one upper part 15, so that the device is hermetically sealed. In the manner known from the aforementioned DE-A-2364565, the air is extracted and welding and fitting of the compressible lower foil on the packaged product is performed. The package made in this way has, as shown in Figure 6, one welded edge 16 and one section of compressed lower foil 7 and upper foil 10 that fits tightly on the packaged product. Further, between the sections of the foils that rest on the product and the welded edges 16, there is a section 17 in which the lower foil 7 and the upper foil 10 are tightly abutting each other without being welded to each other.

U sledećem po redu uređaju 6 za odsecanje, ovako obrazovane kutije, prikazane na slici 6, isecaju se iz trake folije poprečnim i uzdužnim rezanjem i stavljaju na transportersku traku 18. In the next cutting device 6, the boxes formed in this way, shown in Figure 6, are cut from the foil strip by transverse and longitudinal cutting and placed on the conveyor belt 18.

Kod prikazanog primera izvođenja mašina za pakovanje ima na izlaznoj strani jedan, samo šematski prikazan, uređaj 19 za naknadno skupljanje. On je tako izveden da se u njega uneto pakovanje, tipa prikazanog n slici 6, izlaže toploti sa svih strana, tako da dolazi do naknadnog skupljanja donje folije 7 i gornje folije 10, tako da se odsečak 17 usled skupljanja smanjuje i tako urađeno pakovanje 36 poprima izgled prikazan na slici 7. Kao rezultat, donja folija 7 i gornja folija 10 potpuno naležu na zapakovan proizvod tako da odsečak 17 otpada. In the shown embodiment, the packaging machine has one, only schematically shown, device 19 for subsequent shrinking on the output side. It is made in such a way that the packaging inserted into it, of the type shown in Figure 6, is exposed to heat from all sides, so that the subsequent shrinkage of the lower foil 7 and the upper foil 10 occurs, so that the section 17 is reduced due to shrinkage and the package 36 made in this way takes on the appearance shown in Figure 7. As a result, the lower foil 7 and the upper foil 10 completely rest on the packaged product so that the section 17 falls off.

Uređaj 19 za naknadno skupljanje može, sjedne strane, biti tako izveden da se na pakovanje kratkotrajno deluje vodom na temperaturi ispod tačke ključanja. Zagrejana voda izaziva intenzivno i brzo skupljanje, a da na proizvod ne utiče nepovoljno svojom toplotom. Alternativno, može uređaj 19 biti izveden tako da na slobodno pakovanje deluje vrućim vazduhom. The device 19 for subsequent shrinking can, on the other hand, be designed in such a way that the package is treated for a short time with water at a temperature below the boiling point. Heated water causes intense and rapid shrinkage, without adversely affecting the product with its heat. Alternatively, the device 19 can be designed to act on the free package with hot air.

Izvođenje prikazano na slici 2 modifikovano je utoliko što se proizvod 9' može upakovati tako da posle unošenja u posudu 8 izrađenu dubokim izvlače-njem štrči iznad ravni donje folije, kako je to prikazano na slici 2. Odgovarajući su delovi označeni istim pozivnim brojevima. Osnovna je razlika u dovođenju gornje folije 10 i u konstrukciji uređaja 25 za isisivanje vazđuha i za zavarivanje. The embodiment shown in Fig. 2 is modified in that the product 9' can be packaged so that after being placed in the container 8 made by deep drawing, it protrudes above the plane of the lower foil, as shown in Fig. 2. The corresponding parts are marked with the same reference numbers. The main difference is in the introduction of the upper foil 10 and in the construction of the device 25 for exhausting air and for welding.

Kao što je prikazano na slici 2, sa obe strane gornje folije postavljene na nosaču 11 predviđen je transportni lanac 21 koji vrši kružno kretanje, a koji na nekom odstojanju ispred uređaja 25 za isisivanje vazđuha i za zavarivanje preko kotura 22 za promenu pravca prevodi gornju foliju 10, držeći je za bočnu ivicu, i zatim prenosi kroz uređaj 25 za isisivanje vazđuha i za zavarivanje da bi je oslobodio na nekom odstojanju od uređaja 25 za isisivanje vazđuha i za zavarivanje. Na delu putanje između kotura 22 za promenu pravca i ulazne strane uređaja 25 za isisivanje vazđuha i za zavarivanje postavljen je uređaj 23 za zagrevanje gornje folije 10. Taj uređaj može biti izveden bilo kao grejna površina na dodir, bilo kao površina za zagrevanje zračenjem. As shown in Fig. 2, on both sides of the upper film placed on the support 11, a circular movement transport chain 21 is provided, which at some distance in front of the air suction and welding device 25 over the roller 22 to change the direction translates the upper foil 10, holding it by the side edge, and then conveys it through the air suction and welding device 25 to release it at some distance of devices 25 for air extraction and welding. On the part of the path between the rollers 22 for changing the direction and the entrance side of the device 25 for exhausting air and for welding, a device 23 for heating the upper foil 10 is placed. This device can be performed either as a touch heating surface or as a radiation heating surface.

Uređaj 25 za isisivanje vazđuha i za zavarivanje ima u već opisanom donjem delu 13 jedan gornji deo 26, koji se može pomerati gore-dole u smeru strelice 24. Gornji deo 26 ima na svojoj strani okrenutoj ka donjem delu 13 jednu šupljinu 27 koja je tolika, da može da obuhvati deo robe 9' koja se pakuje a koji štrči preko ravni donje folije. The device 25 for extracting air and for welding has in the already described lower part 13 an upper part 26, which can be moved up and down in the direction of the arrow 24. The upper part 26 has, on its side facing the lower part 13, a cavity 27 which is so large that it can include part of the goods 9' to be packed and which protrudes over the plane of the lower foil.

U toku rada su radi dovođenja oba dela 13 i 26 držana u razdvojenom položaju, kako je prikazano na slici 2, tako da se popunjeno pakovanje može uncti pokriveno donjom i gornjom folijom. Tada se oba dela tako dovedu jedan do drugoga da dodirna površina bude u ravni donje folije, tako da ivice donje folije i gornje folije naležu jedna preko druge. Na taj način dolazi u uređaju za isisivanje vazđuha i za zavarivanje do sabijanja gornje folije omogućenog prethodnim zagrevanjem. Skupljanje na proizvodu nastaje kao i kod prvog izvođenja kako na donjoj, tako i na gornjoj foliji. Kao i kod prvoopisanog izvođenja sledi jedno naknadno skupljanje u uređaju 19 za naknadno skupljanje usled čega obrazovano pakovanje 37 poprima izgled prikazan na slici 8, tj., najpre se odsečak 17 pakovanja koji postoji između područja proizvoda i ivice 16 smanjuje. In the course of work, both parts 13 and 26 were kept in a separate position, as shown in Figure 2, so that the filled package can be removed, covered with the lower and upper foil. Then both parts are brought together in such a way that the contact surface is in the plane of the lower foil, so that the edges of the lower foil and the upper foil lie on top of each other. In this way, the compression of the upper foil, made possible by the previous heating, occurs in the device for extracting air and for welding. Shrinkage on the product occurs as with the first performance both on the lower and on the upper foil. As with the first described embodiment, one subsequent shrinking follows in the device 19 for subsequent shrinking, due to which the formed package 37 takes on the appearance shown in Figure 8, i.e., first the segment 17 of the package existing between the product area and the edge 16 is reduced.

Izvođenje prikazano na slici 3 načinjeno je za prihvatanje proizvoda 9" koji treba pakovati. Ovaj proizvod, kako je prikazano na slici 3, štrči znatno iznad ravni donje folije 7. The embodiment shown in Figure 3 is made to accept a product 9" to be packaged. This product, as shown in Figure 3, projects well above the plane of the lower foil 7.

Pored uređaja 4 za oblikovanje u kome se dubokim izvlačenjem oblikuje donja folija, na odsečku između kotura 22 za promenu pravca i ulazne strane uređaja 35 za isisivanje vazđuha i za zavarivanje, znači u području u kome je kod drugog izvođenja predviđen uređaj 23 za zagrevanje, predviđen je dodatni uređaj 28 za oblikovanje. On ima na strani gornje folije okrenutoj proizvodu jedan nepokretan deo 30 koji odgovara gornjem delu uređaja 4 a na suprotnoj strani ravni 1 folije jedan gornji deo 32 koji se naizmenično primiče i odmiče u smeru strelice 31. Gornji deo odgovara donjem delu uređaja 4 za oblikovanje. Uređaj 28 za oblikovanje radi na isti način kao i uređaj 4 za oblikovanje i izrađuje dubokim izvlačenjem jedan deo 33 kutije koji štrči nagore preko proizvoda koji isto štrči nagore. In addition to the shaping device 4 in which the lower foil is shaped by deep drawing, on the section between the rollers 22 for changing the direction and the inlet side of the air extraction and welding device 35, i.e. in the area where the heating device 23 is provided in the second embodiment, an additional shaping device 28 is provided. It has on the side of the upper foil facing the product one stationary part 30 that corresponds to the upper part of the device 4 and on the opposite side of the plane 1 of the foil, one upper part 32 that alternately approaches and moves away in the direction of the arrow 31. The upper part corresponds to the lower part of the device 4 for shaping. The forming device 28 operates in the same manner as the forming device 4 and produces by deep drawing a portion 33 of the box which protrudes upwards over the product which also protrudes upwards.

Uređaj 35 za isisivanje vazđuha i za zavarivanje razlikuje se od uređaja opisanog na slici 2 samo po tome što šupljina 33' ima jednu dimenziju koja je prilagođena za prihvat dela 33 kutije. The air extraction and welding device 35 differs from the device described in Figure 2 only in that the cavity 33' has one dimension adapted to receive the box part 33.

U radu se proizvod 9" koji se pakuje stavlja iza uređaja 4 za oblikovanje u kutiju načinjenu u donjoj foliji. Ispred uređaja 35 za isisivanje vazđuha i za zavarivanje preko proizvoda se postavlja nasuprot usmerena, dubokim izvlače-njem oblikovana gornja folija, i tako pripremljeno pakovanje se uvodi u uređaj 35 za isisivanje vazđuha i za zavarivanje i u njemu se na napred opisan način iz pakovanja uklanja vazduh i pakovanje se zavari i skuplja. Potom sledi razdvajanje pakovanja na napred opisan način. U uređaju 19 za naknadno skupljanje vrši se naknadno skupljanje kojim se postiže pakovanje 38 prikazano na slici 9, kod koga je odsečak 17 između folije koja naleže neposredno na proizvod i ivice uklonjen skupljanjem. In operation, the product 9" to be packed is placed behind the device 4 for forming in a box made in the lower foil. In front of the device 35 for air extraction and for welding, an oppositely directed, deep drawing shaped upper foil is placed over the product, and the package thus prepared is introduced into the device 35 for air extraction and for welding, and in it the air is removed from the package in the manner described above and the package is welded and collected. separation of the package in the manner described above In the subsequent shrinking device 19, the subsequent shrinking is carried out, which achieves the packaging 38 shown in Figure 9, where the section 17 between the foil that lies directly on the product and the edges is removed by shrinking.

Kod napred opisanih primera izvođenja uređaj 19 za naknado skupljanje uvek je postavljen u blizini izlazne strane mašine za pakovanje. Isto tako je moguće da se uređaj 19 za naknadno skupljanje predvidi odvojeno od mašine za pakovanje i da se sa izlazne strane mašine pakovanja odsečena uređajem 6 za odsecanje prenesu u odvojeno postavljen uređaj 19 za naknadno skupljanje i da se tamo izvede postupak naknadnog skupljanja. Ipak je pogodnije da je uređaj 19 za naknadno skupljanje sastavni deo mašine za pakovanje. In the embodiments described above, the post-shrinking device 19 is always placed near the outlet side of the packaging machine. It is also possible that the device 19 for subsequent shrinking is provided separately from the packaging machine and that the pieces cut off by the cutting device 6 from the output side of the packaging machine are transferred to the separately placed device 19 for subsequent shrinking and that the subsequent shrinking process is performed there. However, it is more convenient that the device 19 for subsequent shrinking is an integral part of the packaging machine.

Na slici 4 prikazan je lanac 21' za transportovanje trake 7 donje folije i lanac 21 za transportovanje trake gornje folije koji u položaju u uređaju 25, odnosno 35, za isisivanje vazđuha i za zavarivanje drže ivice donje i gornje folije tako da se one kreću u jednoj ravni. Figure 4 shows the chain 21' for transporting the strip 7 of the lower foil and the chain 21 for transporting the strip of the upper foil, which in the position in the device 25 and 35, for exhausting air and for welding, hold the edges of the lower and upper foil so that they move in one plane.

Na slici 5 prikazan je lanac u uređaju 28 za oblikovanje u kome se gornja folija bočno zategnuta dovodi u ravan donjeg dela 30. Figure 5 shows the chain in the forming device 28, in which the upper foil is laterally tensioned and brought into the plane of the lower part 30.

U slučaju da upakovan proizvod ima šupljine, kao što je to slučaj a sirom ili sa živinom, može se uređaj za isisivanje vazđuha i za zavarivanje na poznat način izvesti tako da se posle isisivanja vazđuha uvede neki inertni gas za ispunu šupljina u proizvodu. In the event that the packaged product has cavities, as is the case with cheese or poultry, the device for air extraction and welding can be performed in a known manner so that after the air extraction, some inert gas is introduced to fill the cavities in the product.
